I do not recall the jig with the balls. We saw the ladder gauges but not the ones with the ceramic balls. That is an interesting gadget, I wonder how they calibrate that

Here is the link to all my pictures of that visit at NIST:

I think it's not so much the light itself as the heat produced by the lights.
